Chimerigen
IL-2 (mouse):Fc (mouse) (rec.) (non-lytic)
Product Details | |
---|---|
Synonyms | Interleukin-2; Aldesleukin |
Product Type | Protein |
Properties | |
Source/Host | NS1 cells |
Sequence |
The extracellular domain of mouse IL-2 (aa 21-169) is fused to the N-terminus of the Fc region of a mutant mouse IgG2a. |
Crossreactivity | Mouse |
Biological Activity |
Specific Activity: 1-1.5 x106 Units/mg, measured using CTLL indicator cells. |
MW | ~46kDa (monomer) |
Purity | ≥98% (SDS-PAGE) |
Endotoxin Content | <0.06EU/μg protein (LAL test; Lonza). |
Reconstitution | Reconstitute at 100μg/ml in sterile PBS. |
Formulation | Lyophilized from 0.2μm-filtered solution in PBS. |
Protein Negative Control | |
Other Product Data |
Non-lytic: Acts as a long lasting fusion protein which only binds to the receptor. Mutations to the complement (C1q) and FcgR I binding sites of the IgGs Fc fragment render the fusion proteins incapable of antibody directed cytotoxicity (ADCC) and complement directed cytotoxicity (CDC). |
Declaration | Manufactured by Chimerigen. |
Shipping and Handling | |
Shipping | BLUE ICE |
Short Term Storage | +4°C |
Long Term Storage | -20°C |
Handling Advice |
Avoid freeze/thaw cycles. Centrifuge lyophilized vial before opening and reconstitution. |

Interleukin-2 (IL-2) is a 133 amino acid glycoprotein with one intramolecular disulfide bond and variable glycosylation. It is secreted by activated T cells and induces proliferation and maturation of activated T cells, natural killer cells, and lymphokine activated killer cells. IL-2 also stimulates proliferation of antibody-producing B cells, activates neutrophils, and induces mononuclear cells to secrete IFN-γ and TNF-α and -β. Moreover, studies have shown that IL-2 is required for activation-induced apoptosis, an important hemeostatic mechanism in the immune system, which is involved in the maintenance of peripheral tolerance to self-antigens.
